Line ending policies were changed in the parent, dccebddb3b80. To make it easier to resolve downstream merge conflicts after line-ending policies are adjusted this is a separate whitespace-only commit. If you have merge conflicts as a result, you can simply `git add --renormalize -u && git merge --continue` or `git add --renormalize -u && git rebase --continue` - depending on your workflow.
